Seth Dallaire

Seth Dallaire is one of the most influential figures in the rise of retail media as a major advertising channel. As EVP and Chief Revenue Officer at Walmart, he oversees Walmart Connect, the company's retail media network, positioning it as a direct competitor to Amazon Advertising. His work has helped cement retail media networks as a critical pillar of the modern AdTech ecosystem, driving advertiser dollars toward first-party, purchase-intent-driven inventory at massive scale. Dallaire's career trajectory is defined by his foundational role at Amazon, where he served as VP of Global Advertising Sales and helped build Amazon Advertising from a nascent offering into one of the world's largest and most sophisticated digital advertising businesses. His tenure at Amazon gave him deep expertise in leveraging first-party shopper data to create highly targeted, measurable ad products — a playbook he has since brought to Walmart. Before Amazon, he held senior roles at Yahoo, giving him a broad foundation across both publisher-side and platform-side advertising. At Walmart, Dallaire has been instrumental in expanding Walmart Connect's capabilities, growing its advertiser base, and investing in self-serve programmatic tools and measurement solutions. He is widely regarded as a key architect of the retail media arms race, and his moves are closely watched by competitors including Target, Kroger, and Home Depot as they build out their own networks.
